The four sons of Horus were a group of four deities in ancient Egyptian religion who were believed to protect deceased people in the afterlife. Beginning in the First Intermediate Period of Egyptian history, Imsety, Hapy, Duamutef, and Qebehsenuef were especially connected with the four canopic jars that housed the internal organs that were removed from the body of the deceased during the process of mummification. Most commonly, Imsety protected the liver, Hapy the lungs, Duamutef the stomach, and Qebehsenuef the intestines, but this pattern often varied. The canopic jars were given lids that represented the heads of the sons of Horus. Although they were originally portrayed as humans, in the latter part of the New Kingdom, they took on their most distinctive iconography, in which Imsety is portrayed as a human, Hapy as a baboon, Duamutef as a jackal, and Qebehsenuef as a falcon. The four sons were also linked with stars in the sky, with regions of Egypt, and with the cardinal directions.
